Abstract
A hook switch comprises a dielectric base member having series of stationary electrical contact members secured in aligned rows therein; the contact members in one row are offset with respect to the contact members in the other row and they include V-shaped contact sections and terminal sections. A dielectric cover member is latchably secured onto the base member. A movable contact assembly mounted in the cover member includes an operating member and a contact-carrying member. The operating member is linearly movable within an opening in the cover member from a normally inoperative position to an operative position against spring members extending betweeen the operating member and the base member. The contact-carrying member has switch segments isolated from one another, each of the switch segments including an electrical contact element of a specified length and the remaining length being dielectric material so that opposing sets of V-shaped contact sections engage respective switch segments to electrically connect the V-shaped contact sections together when engaging the electrical contact elements or to electrically disconnect the V-shaped contact sections when engaging the diele…
